Wikipedia:Categories, lists, and navigational templates
Simple boxes can often be replaced with a category. It also can be difficult to give more detail than a category can give without the box becoming unmanageably large.
Templates can become ugly or pointless, e.g. by unsightly coloring schemes, size, number of them on the same page, etc. For this reason article series boxes need to be self-evident, while they can't contain much text for definitions or explanations.
Often inadvertently push a POV and suggest that one aspect of a topic is more important than others, being used to advertise obscure topics in prominent places, or asserting project proprietorship. Templates can go to Wikipedia:Templates for deletion if they appear to push POV. Trying to remedy this by adding more templates might lead to the disadvantage described in the previous point.
Can alter the page lay-out without the reason thereof showing on the page itself (e.g. when the template contains a NOTOC instruction, an unclosed div, etc.)
Templates work best when they are not substed. However, this increases server load.
